[QUOTE="Mikecr, post: 1909569, member: 1521"] You could normalize these measurements by taking them to CBTO. With this, you would see that the attribute changing in your barrel is leade [U]angle[/U]. What I have found over the years is that initial tested best CBTO (while off the lands OTL) holds, regardless of throat erosion. In other words, if initial tested best CBTO is OTL, you can log that, and never need to change it for the life of that barrel -with that bullet. NO NEED TO CHASE LANDS Make the choices that mitigate any need to chase lands, or accept fleeting accuracy. [/QUOTE]
